Re: WK2 battery charging
You should be fine as long as the battery is charged when you connect to it. I don't know the make/ model charger you are using but by using the term "maintainer" I assume it will do so at less than 1.5-2.5 amps. That is a maintenance current. A true "smart" charger will exercise the battery and allow slight charge/ discharge. A true smart charger will only apply as much current as is needed.
My advice (for simplicity sake) is to pick up a Battery Tender at your local hardware store or motorcycle shop (buy LOCAL!). They come with pre terminated ring terminal/ SAE pig tails. You fasten the rings on the + and - under the hood and run the SAE connector wherever you like. You can also make your own, like I did, and place it in the tow hook spot so the hood stays closed.
